flfll gua ings are employed. The shaft lthas an intermediate screw-threaded section 30 on a opposite sides of which cones 31 are mounted, the rear cylindrical section of the shaft being smaller than the front cylindrical section to admit vof assembling the parts. Sleeves or bushings 32 re seatedv within the bearing chamber for ed by the inner cylinder 3a. Rings 33 have oppositely dis- 'posed circular recesses 34 in which the respective ends of tapered rollers 35 are seated and arranged so that said rollers will eX- tend beyond the inner and outer surfaces of the walls of said rings and ride upon the inclined outer surface of the cones 31 and upon the inner inclined surfaces of the sleeves or bushings 32; and said rings are held in place by pins 36 tightened in openings in the respective rings so that when the rollers are in place they will be held in assembled position. A ported partition 37 having inclined outer Walls seated against an off-set S of the outer cylinder'2a is provided with a rearward extension 38 screwthrcaded to the inner cylinder to tighten and hold it in place. Said partition forms the front Wall of the annular chamber 7a and closes the front end of the bearing chamber, a packing 39 being preferably employed to prevent leakage. The rear end of Y the sleeve 32 of the rear bearing is seate against a shoulder of the inner cylinder 3* and the frontend of the sleeve 32 of the front bearing is engaged b v the ported'partition and the spacing cylinder 40 is provided between the inner ends of said sleeves. Nuts 41 with lock-nuts 42 on the screwthreaded portion of the shaft are provided to adjust and hold the bearings in place. Lubricant is supplied. to the bearing chamber through a passage 43 in the shaft and a plug 44 is provided to close the inlet of said passage.

Figs. 8, 9 and 10 show another form of anti-friction bearing which will now be described. A front bearing comprises a cone 45 having two race-ways, balls 46 in each of y said race-ways; two separate cup-rings 47 and 4S. a separator in two solid halves 49 and 50 interposedbetween the balls and a shell 51 is spun over the cups permanently iixing the relationship of the cone, balls and cups in a self-contained ball bearing that is adapted to both carry and take the end thrust of the shaft in both directions.

The rear bearing comprises a cone 52 having a race-way, balls 53 in said race-way, a

cup-ring 54 and a split separator 55 held together by pins 56 is` interposed between and carries the ball-s, the same being arranged as yshown to both carry and take the. end thrust of the shaft in one direction."

These bearings are shown as being adjusted and held in place in like manner as the 5, 6 and 7 and it is not epeat the description.
